617824-001 HP SAS 9200-8E 6GBPS 8 Ports PCI-E X8 Low Profile Host Bus Adapter | New Bulk Pack

A Host Bus Adapter (HBA) is a hardware device that connects a computer system to a storage device, such as a hard disk drive, solid-state drive, or tape drive. The HBA provides an interface between the computer’s bus and the storage device’s bus, allowing data to be transferred between them. The HP 617824-001 SAS 9200-8E is an example of an HBA.

The HP 617824-001 SAS 9200-8E is a low-profile HBA that supports up to eight SAS or SATA drives. It connects to the computer’s PCI-Express (PCI-E) x8 slot, which provides high bandwidth and low latency for data transfer. The HBA uses the SAS protocol, which provides faster data transfer rates than SATA.

SAS and SATA Interfaces

The Serial Attached SCSI (SAS) interface is a serial interface that provides high-speed data transfer rates for connecting storage devices to a computer system. SAS is a point-to-point interface, meaning that each device is connected directly to the HBA. This provides better performance and more reliable data transfer than parallel interfaces, such as SCSI.

SAS also provides advanced features, such as error detection and correction, hot-plugging, and support for multiple initiators and targets. These features make SAS ideal for high-performance storage systems, such as enterprise-class servers and storage area networks (SANs).

The Serial ATA (SATA) interface is also a serial interface that provides high-speed data transfer rates for connecting storage devices to a computer system. SATA is a point-to-point interface, similar to SAS, but it is designed for consumer-grade devices, such as desktop and laptop computers.

SATA provides simpler and lower-cost implementations than SAS, but it does not provide the advanced features of SAS. SATA devices can be connected to SAS HBAs using a SAS-to-SATA adapter.

PCI Express (PCI-E) Bus

The PCI Express (PCI-E) bus is a high-speed serial bus that provides connectivity between a computer system’s CPU and other hardware devices, such as graphics cards, network adapters, and storage devices. PCI-E provides higher bandwidth and lower latency than previous generation PCI and PCI-X buses.

PCI-E is a point-to-point bus, meaning that each device is connected directly to the CPU. This provides better performance and more reliable data transfer than shared-bus architectures, such as PCI and PCI-X.

PCI-E is available in different sizes, or “lanes”, ranging from x1 to x32. The more lanes a device uses, the higher the bandwidth it can achieve. The HP 617824-001 SAS 9200-8E connects to the computer’s PCI-E x8 slot, which provides up to 8 gigabits per second of bandwidth.

Low-Profile HBA

The HP 617824-001 SAS 9200-8E is a low-profile HBA, meaning that it is designed to fit in a computer system with limited space. Low-profile HBAs are typically used in small form-factor computers, such as rack-mount servers and blade servers.

Low-profile HBAs have a shorter PCB (printed circuit board) and a lower profile bracket than standard HBAs. This allows them to fit in smaller computer systems, such as 1U or 2U rack-mount servers, without obstructing other hardware components.

Finally, the HP 617824-001 SAS 9200-8E is a low-profile HBA that provides connectivity between a computer system and up to eight SAS or SATA storage devices. It connects to the computer’s PCI-E x8 slot, which provides high bandwidth and low latency for data transfer. The HBA uses the SAS protocol, which provides faster data transfer rates than SATA.
